To identify township-level high-risk foci of malaria transmission in Yunnan Province, China, along the international border, we retrospectively reviewed data collected in hospitals and clinics of 58 townships in 4 counties during 2011-2013. We analyzed spatiotemporal distribution, especially hot spots of confirmed malaria, using geographic information systems and Getis-Ord Gi*(d) cluster analys...

This paper presents a continuous version of the model of distribution dynamics to analyse the transition dynamics and implied long-run behaviour of the EU-27 NUTS-2 regions over the period 1995–2003. It departs from previous research in two respects: first, by introducing kernel estimation and three-dimensional stacked conditional density plots as well as highest density regions plots for the v...

The reduction of traffic crashes, as well their socio-economic consequences, has captivated the attention safety professionals and transportation agencies. most important activity for an effective road practice is to identify hazardous roadway areas based on a spatial pattern analysis crashes evaluation crash relations with neighboring other relevant factors. For decades, researchers have adopt...

The above testing procedures are all motivated by the spatial autoregressive model of residual errors. So before moving on to spatial regression analyses of areal data, it is appropriate to consider certain alternative measures of spatial association that are also based on spatial weights matrices. By far the most important of these for our purposes are the so-called G-statistics, developed by ...

The paper provides an assessment of Tuz Gölü, a site in Turkey proposed for the radiometric vicarious calibration of satellite sensors, in terms of its spatial homogeneity as expressed in visible and near-infrared (VNIR) wavelengths over a 25-year period (1984–2009). By combining the coefficient of variation (CV) and Getis statistic (Gi*), a spatially homogenous and temporally stable area at le...

Background and Objectives: Dementia is a chronic disease that imposes a huge financial and social burden on the health system. Knowledge of the prevalence of dementia is essential for healthcare planning and ensuring that there is an adequate service for people with the condition. Considering that the prevalence and geographical variation of dementia are not well known in Iran, the present stud...

This study assessed the spatial dependence of daily tobacco consumption and how it is spatially impacted by individual neighborhood socioeconomic determinants, facilities before after a smoke-free implementation. Individual data was obtained from Bus Sante, cross-sectional survey in Geneva. Spatial clusters high low were using Getis-Ord Gi*. Daily not randomly clustered Geneva may be independen...

As a form of tenancy in common, heirs’ property presents numerous obstacles to owners’ ability to build wealth. This is because the titles for such properties are unclear or “clouded” and cannot be uses as collateral for loans. The bulk of the heirs’ property literature focuses on rural, African American landholdings in the Black Belt South, where the extent of heirships have been estimated to ...

BACKGROUND An improved understanding in transmission variation of kala-azar is fundamental to conduct surveillance and implementing disease prevention strategies. This study investigated the spatio-temporal patterns and hotspot detection for reporting kala-azar cases in Vaishali district based on spatial statistical analysis. METHODS Epidemiological data from the study area during 2007-2011 w...
